bpf: Define sock security related BTF IDs under CONFIG_SECURITY_NETWORK
There are warnings reported from resolve_btfids when building vmlinux
with CONFIG_SECURITY_NETWORK disabled:
WARN: resolve_btfids: unresolved symbol bpf_lsm_sk_free_security
WARN: resolve_btfids: unresolved symbol bpf_lsm_sk_alloc_security
So only define BTF IDs for these LSM hooks when CONFIG_SECURITY_NETWORK
is enabled.
Fixes: c0c852dd1876 ("bpf: Do not mark certain LSM hook arguments as trusted")
